hi everyone, I'm planing to make a racing game, may be same concept with http://helloracer.com/racer-s/  You can take a look my work here: https://dl.dropboxusercontent.com/u/86585940/BabylonWave/optimized2/index.html My target is mobile browser, with best performace as I can optimize. This is what I approach: - Set screen resolution to 640x480 - Disable Anti Alisas. - Merge all textures to single file (1024x1024) - change maxZ to lower value (Frustum Culling)
